Case Type   : 资源池化故障模式库
Case Name   : pg_log无权限-pg_log目录无权限
Create At   : 2025/04
Owner       : haomeng
Description :
    1、查看集群状态
    2、运行tpcc业务
    3、修改主节点pg_log目录为无权限访问状态
    4、查看业务运行情况
    5、重启集群,查看集群状态
    6、恢复pg_log目录权限
Expect      :
    1、集群状态正常
    2、运行业务成功
    3、修改主节点pg_log目录权限成功
    4、业务运行正常无影响
    5、重启集群失败
    6、pg_log目录权限恢复正常
